B、硫在氧气中燃烧发出明亮的蓝紫色的火焰,所以错误.

C、铁丝在氧气中燃烧的现象是:剧烈燃烧,火星四射,放出大量的热,同时生成黑色固体,所以正确.

D、浓盐酸有挥发性,挥发出的氯化氢气体极易溶于水,能和空气中的水蒸气结合形成盐酸的小液滴,故在瓶口有白雾出现,不是白烟,所以错误.

故选C.

If you need extra employment support because of a disability, your local job center put you in touch with one of their Disability Employment Advisers(DEA). Disability Employment Advisers can give you help and support regardless of your situation. They can help you find work or gain new skills even if you have been out of work for a long time, or if you have little or no working experience.

Referral service

Your DEA can offer you an employment assessment to identify what type of work or training suits you best and also offer you a work program designed to help disabled people, like the Job Introduction Scheme, WORKSTEP or Access to Work. The DEA can let you know about jobs that match your experience and skills and offer you more work information.

Employment assessments

An important employment assessment can help you identify your abilities. Your employment assessment will usually take place at your local Job centre. You will have an interview with your DEA, which is an opportunity for you to talk about your skills and abilities and any previous working experience you may have. As part of the assessment, you may be asked to carry out some practical tasks and written work. These tasks will be similar to common tasks involved in various types of work. The assessment may take half a day or longer, depending on your individual needs. The DEA will discuss the length of your assessment with you beforehand.

After the assessment

You and your DEA will talk about your assessment and agree on an action plan to help you achieve your job goals. Your action plan may include training or taking part in the “Work Preparation” program.
